ABSTRACT
The physical substance of the frequency characteristics of material under the effect of electromagnetical field is discussed in this paper. According to the frequency characteristics of the material's structure properties expressed under the effect of external electromagnetical field their relationship has been studied and an analytical model between the material's properties and the frequency characteristics has been set up. The study has shown that the metal material under the effect of electromagnetic field has its frequency characteristic value, depending on which a new electromagnetic testing method can be created.
